Gently fold floured berries into the batter. Spread the batter in the prepared baking pan.

Bake for 1 hour and 15 minutes, or until it tests done. A toothpick inserted in the center of the cake should come out clean.

Optional Vanilla Glaze

In a mixing bowl combine 1 tablespoon of melted butter, 2 cups of confectioners' sugar, 1 teaspoon of vanilla extract, and 2 to 3 tablespoons of milk, or enough to make the icing thin enough to drizzle over the cake. Blend well and drizzle over the cooled cake.
